The nation's largest supplier of bullet-resistant vests to law enforcement agencies is urging its customers to replace vests containing the fiber Zylon, saying they may not be safe.

Second Chance Body Armor said Wednesday it had sent notices to police agencies nationwide. The warning affects about 58,000 Tri-Flex vests and an additional 40,000 Ultima and Ultimax vests with Performance Pacs, the company said in a statement.

New research shows that vests made even partially with Zylon "may fail to perform and result in serious injury or death," it said.

Second Chance, based in Central Lake, Mich., is undergoing reorganization in federal bankruptcy court after being targeted in numerous lawsuits claiming its vests made with Zylon are defective.

The company said it would ask the court to devise a procedure for vest owners to make claims arising from the latest warnings.

"While Second Chance has not received any reports of field failures of the products in question, we felt it was our obligation to report these new research findings immediately," said Matt Davis, the company's vice president of sales and marketing.

"The safety and well-being of all the officers who wear our body armor is of primary importance to Second Chance, and we strongly encourage all officers to replace ballistic vests that contain Zylon as quickly as possible," he said.
